Hi all. Since yesterday my teens been coughing every so often, maybe every half hour its 'cough cough' so just 2 or so coughs then 30 or so minutes later will do it again. He said he was coughing at school but didnt get sent home or anything. Is this type of cough OK or does he need a test? Just asking as my mate has said he is not coughing enough so I felt silly trying to get a test. AIBU to get one and isolate?
